The roofs of Prague castle are covered either with classic clay tiles bedded in mortar or with historical rectangular slate tiles. In recent years, it has become necessary to restore the pantiles of a number of buildings. The renovation was carried out mainly on some parts of the western, central and northern wings of the New Palace, the Old Royal Palace and the blacksmith’s workshop in Lumbe Garden.
ROOF WITH HISTORICIST PATINA
An important part of the castle compound which has undergone complete renovation is the central wing of the New Palace, mentioned above. The eastern part of its roof, measuring 1,440 m² in size, received new pantiles with ceramic tiles engobed with an antique finish. The ecru tile patina effect gives the roof a historicist look and was achieved by partial engobing, where a coloured glass mixture was applied to the tiles before burning. A special mortar, not containing any cement, was used. The laying method itself has remained unchanged for decades and maintains the original historical design. For 40 days, three groups of roofers, carpenters and tinsmiths took turns working on the roof. 189 pallets of clay tiles and 22 pallets of mortar were used.
All materials and technological processes used during the reconstruction of the Prague Castle roofs were discussed with and approved by the Heritage Conservation Department of the Office of the President, whose purpose is to carry out state administration regarding heritage conservation of the Prague Castle as a national heritage site.
I believe the reconstruction of the roofs has been successful – the quality of all types of roofing and its flawless functionality is a matter of course. It is very important for the overall image of the historical buildings to maintain the shape and type of roofing as well as its colouring.
